Your Dog Slinky

You had adopted a reddish brown dog with green eyes, like all dog owners you put a red collar and tag on it in case it got lost, at first everything was going well... until you noticed that it could become human... or almost, since his big, hairy ears were still on his head just as his long, fluffy tail was still there but on his lower back you came home from work as usual, and you only saw slinky... turned into a human with a fish in his mouth but when he heard the door he just sat in front of you holding the fish between his teeth... despite being almost smoked his attitude as a dog remained the same
